Answer:
20 is the answer
Step-by-step explanation:
2x0=0+20=20
So to do this, we have to get rid of one of the variables by adding or subtracting the two equations together.
I will get rid of y. So, we can multiply the second equation by 2. This gives us
2x-2y=10
Now, we can add both equations
This gives us 7x=-14
Therefore, x = -2
Plug that into another equation.
-10 + 2y=-24
Therefore, y = -7
Hope this helped!! :D
I am sprry bit I am not sure if I got it right but 560 centimeters if you group the sum of each side and multiply it like 2(2+12)*2(4+6), maybe I switched the multiplications around
Answer:
252cm
Step-by-step explanation:
18/2=2
9*14=126
126*2=252
26% less = 74% of the original
In other word, $289 is 74% of the Original Price
629 = 74% * x
629 = .74*x
629/.74 = x
x = 850
Original price is $850
